Description and figure of a new species, the discovery of 
which was announced in the Transactions for Jan., 1886. 
Dewberries—More About the. L. H. Bailey. (Am. Gard. xii. 
82-84, figs. I, 2, 3). 
A new variety is figured and described, viz : Rubus Canadensts, 
var. ¢uvisus, in regard to which the author says: “ This variety 
grows in open woods here at Ithaca, where it looks very different 
from either Rubus Canadensis or R. villosus. Professor Dudley, 
who has given it considerable attention, thinks that it may be 
found to possess sufficient distinctness to make it worth specific 
rank. It is certainly more unlike the type of R. Canadensis 
than is the var. roribaccus. There isa key at the end, in which 
the author makes three divisions of our Rwdz, viz.: Dewberries, 
Blackberries and Raspberries, and compares the wild with the 
allied cultivated varieties. 
Diatoms—Deformed. J. D. Cox. (Reprint from Proc. Am, 
Soc. Micros. Thirteenth Ann. Meeting, 1890, pp. 178-183, 
illustrated). 
Abnormalities or sports are described in the genera Vavicula, 
Triceratium, Biddulphia, Eunotia, Licmophora, Rhaphonets, 
Cymatopleura, Grammatophora, Mastogonia, Stictodiscus, Coscino- 
discus, Arachnodiscus, Actinoptychus, Amphitetras, Epithemia 
and Witzschta. The author hints at the possibility of abnormali- 
ties in structure being more common than generally supposed and 
that where such abnormalities result in symmetrical markings or 
outlines new varieties or species may be described from them. In 
conclusion he says: ‘‘ Consideration of this sort may assist us in 
reducing the enormous catalogue of species in the Diatomacee, 
a consummation devoutly to be wished.” 
Disease of Geraniums. B.T. Galloway. (Journ. Mycol. vi. 114, 
115, illustrated). 
From preliminary observations the conclusion is reached that 
this disease is the.same as that reported from France, which is said 
to be caused by a Baczllus and which has received the provisional 
name of B. caulicolous, Pr. and Del. 
European Aliens in America. D. T. A. Cockerell. (Journ. Bot., 
xxix. 76-78). 
The following species are mentioned: Ranunculus acris,
